rspiro: Implementation of Spirometry Equations
Implementation of various spirometry equations
in R, currently the GLI-2012 (Global Lung Initiative;
Quanjer et al. 2012 <doi:10.1183/09031936.00080312>),
the race-neutral GLI global 2022 (Global Lung Initiative;
Bowerman et al. 2023 <doi:10.1164/rccm.202205-0963OC>) and the
NHANES3 (National Health and Nutrition Examination Survey;
Hankinson et al. 1999 <doi:10.1164/ajrccm.159.1.9712108>)
equations.
Contains user-friendly functions to calculate predicted
and LLN (Lower Limit of Normal) values for different
spirometric parameters such as FEV1 (Forced Expiratory
Volume in 1 second), FVC (Forced Vital Capacity), etc,
and to convert absolute spirometry measurements
to percent (%) predicted and z-scores.
